Abstract

We study the influence of photo-bleaching process on third order optical nonlinearities of PMMA/DR1 polymer at 1064 nm by Z-scan technique. The measured results show the coefficient of two-photon absorption decreases and the nonlinear refractive index has not obviously change after photo-induced ultraviolet bleaching.
